Question

All motor vehicles are required to have third party insurance. Any vehicle not using mechanical device is not a motor vehicle. Which is the correct derivation?

• A. All third party insurances relate to motor vehicles
• B. Vehicles not using mechanical device need not have third party insurance
• C. All vehicles must have third party insurance

Hint:

Answer 1

The Correct Option is B

Given the statement: "All motor vehicles are required to have third party insurance," we can derive that:

• Only motor vehicles are mandated by law to obtain third party insurance.

Further information states: "Any vehicle not using mechanical device is not a motor vehicle." This implies:

• Vehicles without a mechanical device do not qualify as motor vehicles under the given definition.

Thus, the logical derivation is:

• Vehicles not using a mechanical device, since they are not motor vehicles, do not need third party insurance.

Therefore, the correct option is: Vehicles not using mechanical device need not have third party insurance.
